Satoru does endorsements and advertising in Japan as well as running a multiple title-winning team in Super Formula and a team in Super GT, something he's been doing since the 1990's. Nakajima is also mentor to his sons, Kazuki and Daisuke, both of whom have established themselves in Japan. Nakajima had a long driving career before appearing in Formula 1 - he won his first Japanese F2 race 9 years before his Grand Prix debut. Satoru still lives on the family farm near Okazaki, and occasionally, when time allows, likes to be involved with the farming.
